I have turned chat off on all of my sites unless there is a rail going. Think about it objectively... what is gained by anything written in chat? Would you believe someone even if they told you exactly what they have? It is really just noise and a distraction, turn the chat off and concentrate on the game.
As Dan Harrington says, for $10 I will tell you what I had, for $20 I will tell you the truth, and for $100 I will show you my cards.
